Leviticus 6:19-23
The Grain Offering of the Priests
6:19 Then the Lord spoke to Moses:
6:20 “This is the offering of Aaron and his sons which they must present to the Lord on the day when he is anointed: a tenth of an ephah of choice wheat flour as a continual grain offering, half of it in the morning and half of it in the evening.
6:21 It must be made with olive oil on a griddle and you must bring it well soaked, so you must present a grain offering of broken pieces as a soothing aroma to the Lord.
6:22 The high priest who succeeds him from among his sons must do it. It is a perpetual statute; it must be offered up in smoke as a whole offering to the Lord.
6:23 Every grain offering of a priest must be a whole offering; it must not be eaten.”
